Let's say I have the following code :
ThreadPool.SetMinThreads(100, 100);
for (int i = 0; i < 100; i++)
{
var request = WebRequest.Create(url);
request.BeginGetResponse(ar =>
{
//inside AsynchCallBack method for request.BeginGetResponse()
var response = (HttpWebResponse)request.EndGetResponse(ar);
string html;
using (var receiveStream = response.GetResponseStream())
using (var readStream = new StreamReader(receiveStream
, Encoding.UTF8))
{
html = readStream.ReadToEnd();
}
Console.WriteLine(Thread.CurrentThread.ManagedThreadId);
}, null
);
}
I'm expecting to see quite a lot of threads when writing to the console the ManagedThreadId - of course I am wrong :) . I generally see only 2 different thread Ids and once in a while 3 thread Ids.
Why this behavior ? What am I missing?
